In signal processing, the term "sampling of the signal" refers to the process of reducing a continuous-time signal to a discrete-time signal, which is defined only on a discrete subset of the time axis, and by means of a suitable encoding, one often assumes that this discrete set is a subset I of the set Z of integers.
